This week saw the release of the Edge Annual Question: What scientific idea is ready for retirement? Many excellent responses were submitted; the Time Lord zeroed in on the various entries dealing with Falsifiability, cause and effect, IQ, and the universe as his faves, while Kate Clancy took a good, hard look at The Way We Produce and Advance Science: "As unadulterated as we may want to envision science, the scientific enterprise is run by people, and people often run on implicit bias."

I think all the Edge contributors should do this for the next installment: Student Rickrolls his teacher in this ingenious quantum physics essay.

"A parliament of owls, a knot of toads, an exaltation of larks" -- but what's a Collective Noun for Mathematicians?

Physicists come together to explore mechanics of collective motion by taking a lead from starlings and sardines.

Ball lightning--often reported but never confirmed, previously dismissed as hallucination--turns out to be real. Per New Scientist: "In 2012, Jianyong Cen and his colleagues at Northwestern Normal University in Lanzhou, China, were observing a thunderstorm in Qinghai, China with video cameras and spectrographs. Purely by chance, they recorded a ball lightning event." Related: Almost No Americans Die From Lightning Strikes Anymore. Why?

Proposed Time Machine Could Also Clone Objects: Access to the past would open new possibilities of more than travel. “It’s like there are 1,000 different particles… but in fact they’re all the same particle you sent in the beginning... You just have all these temporary copies emerging from and going back into these wormholes.”

The Taste of Electrical Current. "It was sometime around 1752 that Johann Georg Sulzer decided (for reasons best known to himself) to put the tip of his tongue between two plates of (different) metal whose edges were in contact. The results were, quite literally, shocking." The taste of electric currents (part 2 of 2): Enhancing Saltiness with Cathodal Current.’

Bell's Theorem, Quantum Entanglement, and The Experiment That Forever Changed How We Think About Reality.

Particle accelerators join fight against brain cancer. Accelerator technology could be key to developing an effective treatment for a type of brain tumor currently considered incurable.

Teleology Rises From the Grave. "In his 1790 Critique of Judgment, Kant famously predicted that there would never be a “Newton for a blade of grass.” Biology, he thought, would never be unified and reduced down to a handful of mechanical laws, as in the case of physics. This, he argued, is because we cannot expunge teleology (goal-directedness) from living systems. The question “what is it for?” applies to living structures in a way that has no corollary in physics."

Infinite Series: when the sum of all positive integers is a small negative fraction. Yes, negative. "This post involves math. Really bizarre, brain-melting math. The math itself is actually not that complicated—I promise!—but the result will carve out a piece of your soul and leave hollow space." But there were some nuances that the Bad Astronomer missed: here's a bit more on the weirdness of infinite series, written by Greg Gbur in 2010, and a slightly more technical take by Mark Chu-Carroll.

The Latest Update in the Hydrino Saga. "Real scientists, doing real work, don't pull nonsense like this. Mills has been promising a commercial product within a year for almost 25 years. In that time, he's filed multiple patents, some of which have already expired! And yet, he's never actually allowed an independent team to do a public, open test of his system. He's never provided any actual data about the system!"
